Hello all you smart vintage folk out there! Still scanning old family photos and came across this one of yours truly at less that 1-year of age seriously contemplating this thing I am holding and looking for ways to modify it. Any Idea of the brand of this particular fin. I did not see it in any of the 1950's Voit or US Divers catalogs. Thought at first it might me a Voit SailFin but it does not match the pictures. Other than facial hair, my body style really hasn't changed all that much over time.
